The twins might not be the smartest guys on the team, but they both saw the way Kita's eyes were drawn to Atsumu's chest.

Which, of course, made Atsumu preen and tighten his core to flex, showing off his abs and chest and turning just a bit more to show off his entire front to Kita.

Neither twin had much in the way of shame, but Atsumu had even less of it. He shot a smirk at Osamu, who scowled at him. "Why don't you join us, Kita-san?" he asked. "I'll wash your back for you! Samu can attest I'm good at it."

"You haven't washed my back since we were ten," Osamu deadpanned. "And you sucked at it."

"Oi!"
